Abstract: To accomplish the task of removing foul air, the malodor ventilation apparatus has attachment members such as suction cups or a hook for easy installation in different locations. The apparatus has an inlet port for the intake of objectionable air and an outlet port to expel scented refreshed air. Air is drawn into the inlet port by a motorized fan that creates a pressure differential. The objectionable air is drawn through a porous filter. The porous filter is scented by several drops of a liquid scent. This scent is volatized into the malodorous air, changing the air into a pleasing aroma. The scented air is expelled and dissipated through an outlet port of the apparatus. Alternately, the apparatus can comprise a vent duct coupled to exhaust air from the outlet port.

Abstract: The present invention provides a ventilated toilet system with a fan that continuously extracts waste air from the toilet bowl when the toilet is being used.

Abstract: Specific extraction of the oligomers from cotton fibers can be: achieved by a 24-hr incubation at 37° C. with trypsin, chymotrypsin, proteinase K or pepsin, followed by a second 24-hr incubation at 37° C. with cellulase (Trichoderma reesei) or ?-glucosidase. Alternatively, samples were first subjected to cellulase or ?-glucosidase treatment followed by the protease. The residual material is then treated with 0.5N HCI at 100° C. and the extracts analyzed. Fibers treated with cellulase: followed by protease disintegrated and appeared as a cloudy solution, while the fibers treated with protease followed by cellulase retained their structural identity. This analysis reveals striking differences between cotton fibers from different varieties with respect to their susceptibility to enzymatic degradation. This protocol can be used to identify biochemical characteristics, which can then be correlated with genetic markers for advances in plant breeding.
